Is this Lower Arm Toast?

Has rust taken so much of the spring pocket that it would be best to replace? Its funny, the passenger arm looks pristine. Hope it is usable but I suspect it is not. Thanks.

No, it may last a while, but the bending a flexing will eventually cause it to break. Get another one. There are plenty out there. Guy on here has a whole set for 100 bucks, great deal..

Re: Is this Lower Arm Toast?

Having just replaced my arms (at least one side, so far), I have to say that your pocket looks just a little worse than mine did. Not much, just a little more pitting than I had, I think. Pic isn't great, but you can kinda tell if you zoom in on it...

Unless you're out carving corners, it's probably fine, but agree with above: they're cheap; just go ahead and replace it...

Unless you have a wildly original car. In that case, get it cleaned up and salvage it.

Re: Is this Lower Arm Toast?

Appreciate the advice. I will look for a replacement lower since I would kind of like to auto-x it one day. I am replacing the uppers already with aftermarket arms to improve geometry. Thanks again.

Maybe a good time for tubular lowers? Stock lowers have crappy ball joint holes, just did a front end kit the other day for customer, lower ball joint FELL out.....just go tubular so you don't have to worry when it comes time for autox.

What uppers did you do?

David – It looks like there’s some pretty deep rust there. It even looks like there’s a pinhole in the pocket at about the 3 O’clock position of the shock hole. We’re not saying this because we’d love to sell you some new arms, but that looks to be too rusty to use. We suggest replacing it with a much better stock replacement or a better engineered tubular arm.

Re: Is this Lower Arm Toast?

Yes that is is pinhole you can see there and the scale is pretty deep.. The upper arms are from Mark at SC&C.. Years ago he guided me on a few decisions regarding the car and displayed a heroic amount of patience dealing with my numerous newbie questions. I never forgot, and once budget allowed I tuned to him for the arms. Up until now my goal has been to use the stock lowers since I could meet my handling/performance goal with them (and save some money). But now.. with the cost of new delrin bushings, new ball joint, find a newer/better lower, and labor time I am reevaluating. Seems to me I would only be a few hundred more dollars away from tubular lowers (and a lot less headache).

Mr. Hotchkis - I just purchased your TVS system front and rear (minus the arms). Great bang for the buck. Just wanted to let you know I had not left you out.. Again, after alot of research I could meet my handling goal with leaf springs and save a bunch of money. Put me in the drawing for the free subframe connectors please.. haha. Thanks for the help.

this Lower Arm is Toast

yeah toasted....its already apart. just get another one, sandblast and paint. press in a moog ball joint and some inner bushings and be done. I have seen some posts on certain lower ball joints not fitting tight, I have not seen this but it would be apparent. the last set of lowers I refurbished had plenty of bite on the ball joints, they (moog) went in extremely tight and are still in there just fine with a big block sitting above. I think you would be able to figure out a ball joint fittment issue when you press them in.
